management solutions for SynOptics System 5000 structured
networking applications. Occupying a single slot in the Model
5000 chass the FDDI modules support high-bandwidth,
fault-tolerant applications for mission-critical FDDI networks.
THE SYSTEM 5000 SOLUTION
SynOptics' System 5000 represents the
industry's first product family aimed at delivering a structured
networking solution for today's legacy networks while providing a
migration path to future LAN technologies.
The Model 5000 is designed to support highly-segmented enterprise
networks by providing a central point of integration and administration
for distributed environments. Residing in the network center, the
Model 5000 unites distributed LattisSphere(tm) System 3000- and
System 2000-based Ethernet, Token Ring and FDDI networks as a
single, cohesive system, optimizing the use of centralized
network resources such servers, bridges and routers.
The Model 5000 also includes a built-in path to the high-speed switching
technologies of the future, enabling customers to incrementally
migrate their shared-media LANs to switched backbone networks
without sacrificing existing investments.
FDDI HOST AND MANAGEMENT MODULES
SynOptics' System 5000 FDDI modules work together to support a
variety of high-speed network configurations. Operating over the
FDDI backplane on the Model 5000 chassis, the modules can access one
or more of five available 100 megabit per second (Mb/s) data paths
for maximum configuration flexibility. The modules can also be isolated
from the hub backplane to establish independent, stand-alone FDDI
networks.
Two types of System 5000 modules are available: host
modules and network management modules.
SYSTEM 5000 FDDI HOST MODULES
SynOptics offers three different System 5000 FDDI host modules:
the Model 5904 Multi- mode Fiber Host Module, the Model 5904-2SM
Single-mode Fiber FDDI Host Module, and the Model 5905 Unshielded
Twisted Pair FDDI Host Module.
The Model 5904 offers six multi-mode fiber media interface connector
(MIC) Master (M) ports to support host connections up to 2 kilometers
over 62.5/125 m and 50/125 m fiber optic cabling.
The Model 5904-2SM includes four multi-mode fiber and two single-mode
fiber MIC M ports. The single-mode ports support connectivity up to
20 kilometers over 8.5/125 m single- mode fiber optic cabling.
The Model 5905 offers six RJ-45 modular receptacles to support high-speed
host connections up to 100 meters over high-performance Category 5
unshielded twisted pair cabling. The module also operates over Type 1 and
Type 2 shielded twisted pair cabling.
The modules are fully compatible with industry standards, including the
International Standards Organization's (ISO) 9314-1 Physical Protocol (PHY)
and Physical Medium Dependent (PMD) standards, as well as the American
National Standards Institute's (ANSI) X3T9.5 Station Management
(SMT) version 7.3 specification.
The Model 5904, Model 5904-2SM and Model 5905 also include 512 KBytes of
DRAM to run connection management in stand-alone mode when the modules are
isolated from the backplane. An additional 512 KBytes of EPROM contains boot
and system code, while 8 KBytes of non-volatile RAM is available
for configuration storage and restoration.
MODEL 5910S FDDI NETWORK MANAGEMENT MODULE
Two System 5000 FDDI
network management modules are offered: the Model 5910S
Multi-mode FDDI Network Management Module and the Model 5910S-SM
Single-mode FDDI Network Management Module.
The Model 5910S offers two multi-mode fiber A and B MIC ports to support
primary and secondary links up to 2 kilometers over 62.5/125 m and
50/125 m fiber optic cabling. The Model 5910S-SM is identical
to the Model 5910S, with the exception of two single-mode fiber A
and B MIC ports to support primary and secondary connections up
to 20 kilometers over 8.5/125 m single-mode fiber optic cabling.
The A and B fiber ports can be configured to support a variety of
applications, including peer, tree, null-attached and fail-safe
dual-homed configurations. Both modules feature full
compatibility with FDDI SMT, PMD and PHY standards, as well as a
resident Simple Network Management Protocol (SNMP) agent. In
addition, an on-board SNMP-to-SMT proxy agent allows SNMP-based
management stations to access SMT-specific data.
System 5000 FDDI network management modules use the Common
Management Bus (CMB) on the Model 5000 chassis backplane to
communicate with FDDI host modules installed in the hub. The network
management modules collect, process and condense specific performance
and activity data at the network, hub, module and port levels. The
SNMP-to-SMT proxy agent translates the information and forwards
it in-band to a SynOptics Optivity(tm) or other SNMP-compatible
network management station for further review. A front-panel
RS-232 serial communications port is also available for
transmitting SNManagement information out-of-band at speeds up
to 19.2 kilobits per second (Kb/s).
The modules include 2 MBytes of Flash memory, with an additional
2 MBytes of EPROM available for local loading of the base image
code should the Flash image be invalid. A full 4 MBytes of DRAM
simultaneously supports execution of SMT, SNMP and image downloads
to Flash memory.
MODULE CONFIGURATION
The System 5000 FDDI architecture
incorporates software-controlled backplane assignment logic on
all host and network management modules, enabling each board to
access one or more of the five backplane paths. The hub's
default mode of operation supports two FDDI networks, each with a
primary path, a secondary path and a shared local path, which
supports intelligent insertion of FDDI devices on the network.
Modules can be selectively assigned to either network through the
network management system or via a front-panel service port on
the Model 5000 hub.
The FDDI modules also support a variety of other configurations,
depending on how the backplane paths are utilized.
Isolating each module from the backplane enables up to
14 unmanaged FDDI segments to be supported by a single Model 5000
hub. By switching host module M ports between two sets of path
traces, users can establish up to 28 100 Mb/s FDDI segments in a
single hub for supporting user data.
FDDI MANAGEMENT
Each System 5000 FDDI network management module
contains three MAC elements, which can be assigned to any of the
five backplane paths through software control. The System 5000
architecture supports multiple NMMs to manage all FDDI paths
running on both networks within the hub.
If only one network management module is installed in the hub,
users can selectively use software to swap it among networks to
perform management operations on all FDDI paths. When two network
management modules are present, all paths on both networks can be
managed simultaneously.
FDDI Agent Release 1.0, working with the Optivity(tm) network management
system, sorts full management capabilities at the network, hub,
module and port levels. From a central management console, network
managers can obtain a host of performance statistics to determine specific
ring utilization levels. A network-level fault correlation feature identifies
those links and MACs with the worst error rates, helping network
managers locate potential trouble spots in the network. Physical
topology mapping of the FDDI network is also supported, as well
as a logical ring topology feature with trunk-ring wrap detection
capabilities.
DISPLAYS AND INDICATORS
The System 5000 FDDI modules include a series of front-panel LED indicators
to report module and port status at a glance. The Model 5910S and Model
5910S-SM include a module- level annunciator LED to indicate overall module
status, as well as individual LEDs to report network configuration and
station, port and path status. In addition, a four-character
front-panel alphanumeric display reports self-test and general
board operational status.
The Model 5904 and Model 5904-2SM also offer a module-level annunciator
LED to report overall module status. A series of network configuration
LEDs indicate which FDDI network the modules are attached to or whether
they are isolated from the backplane paths. A set of port-level
indicators report whether individual ports are active, if a fault
has been isolated to the port, or if the port is on the primary
or secondary network path.
